Details

Inspect one public HTTPS endpoint without credentials or payment. Validate the URL, make one bounded GET request, and report whether its HTTP 402 x402 or MPP payment offers are parseable and internally consistent. Return protocols, prices, currencies, networks, recipients, expiries, conflicts, and a safe next action. Never sign, pay, or broadcast a transaction.

Collect Payment Endpoint

Goal: Collect and normalize exactly one public HTTPS endpoint to inspect without credentials or payment. | Inputs: A caller-supplied HTTPS URL, including any non-secret query values required to reach its unpaid payment challenge. | Outputs: One normalized HTTPS URL and an explicit statement that the workflow will use GET without authentication, signing, or payment. | Constraints: Reject user information, credential-like query keys, non-HTTPS targets, localhost, private or reserved IPs, nonstandard ports, and requests that require POST, cookies, or authorization headers. Do not collect a wallet key, API key, payment credential, or personal data.

Frequently Asked Questions

How do I connect this workflow to my local agent like OpenClaw or Claude Code?

You can install the local MCP server by opening a terminal and running:

Install commands

npm install -g @agentpmt/mcp-router
agentpmt-setup

This will connect you to local agents like Claude Code, Windsurf, Grok Build, Cursor, etc.

Alternatively you can connect to the hosted version with this config block, no installation required:

Hosted MCP config

{
  "mcpServers": {
    "agentpmt": {
      "type": "streamable-http",
      "url": "https://api.agentpmt.com/mcp",
      "headers": {
        "Authorization": "Bearer <AGENTPMT_BEARER_TOKEN>",
        "x-instance-metadata": "{\"client\":\"generic-mcp\",\"platform\":\"remote\"}"
      }
    }
  }
}
